The Spanish international had given the Catalan side a significant injury scare on Wednesday after he trained alone, but just 24 hours later the buccaneering full-back rejoined his team-mates for a full session.
Alba had no problem matching the intensity of his colleagues, meaning that he is no longer a doubt for Saturday's game.
Since the departure of Neymar form the Camp Nou, Alba's importance to the side has increased significantly, with the former Valencia defender now charged with providing the width down the left-hand side, something which he has done to devastating effect, fostering a fine partenership with Lionel Messi.
There was mixed news for Valverde elsewhere though, with Arda Turan once again missing out, though Rafinha did complete the session as normal and could feature in Barca's squad on Saturday.
Ousmane Dembele, meanwhile, continued his comeback and whilst his recovery is thought to be going well, he will not be considered for the trip to the Bernabeu.
